Implement the UI for Deployments

[flippingbits]

This PR implements the UI for deployments. Deployments are now a top-level item in our navigation.

In the UI, you can:

• Create new deployments
• Update deployments
• Get deployments
• Delete deployments
• Read the logs of the deployments

Try it out

You can explore and try out the changes as follows:

• Check out the PR branch
• Install the latest release into your default namespace:

  kubectl apply -f k8s-manifests/minikube-with-postgres-ns-default.yaml

• Add a port forward:

  kubectl port-forward ui 8080:8080

• Spin up the ReactJS application:

  cd ui
  npm start

• Navigate to http://localhost:3000 in your browser

Todos

I left a couple of TODOs, which should be addressed in the future:

• 45

  At the moment, the /api/alpha/deployments/{uuid}/logs endpoint returns ND-JSON, which needs to be manually parsed to turn it into valid JSON. I suggest to let the endpoint return a valid JSON array.

• 46

  At the moment, it seems that the /api/alpha/deployments/{uuid}/logs endpoint returns all logs of the deployment. We should restrict it to the last X lines to prevent performance issues in both the server and the client. We should make X configurable both via a query parameter (e.g., /api/alpha/deployments/{uuid}/logs?limit=X) and via a configuration property in the application.yml.

• 47

  It seems that the SSE-endpoint, /api/alpha/deployments/{uuid}/watch-logs, is slightly unstable. Before using that in the UI, we should further investigate it and make it more robust.
